With the lack of electric seats I would be very wary of accepting the car without sitting in it and checking if you can get comfortable as the manual seats lack any kind of base tilt function, I had one on loan and it had the manual seats which I found dug in to the back of my thighs unless I had the seat pumped up to near full height.
Might be worth sitting in one in a showroom before your order arrives so you will know if it’s any good for you.
